ROWLOCK.

$PEGIFIGATION forming part of Letters Patent No. 532,713, dated January15,1895.

Application filed May 14, 1894.

To all whom it may concern.-

Be it known that I, HENRY W. STONE, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inRowlocks, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

This invention has for its object to provide a row lock which may beattached to the upper side of the gunwale of a boat without any materialweakening of the same, such as is ordinarily caused by the boring ofholes or cutting away portions of the wood forming this gunwale.

Myinvention consists in features of novelty hereinafter fully describedand pointed out in the claims.

Figure I is a side View; and Fig. II is a top view, both views showingthe lock in the socket. Fig. III is a top view of the socket,

' with the lock removed. Fig. IV is a vertical sectionthrough the centerof the fork of the lock, and through the socket. Fig. V is a side viewshowing in section a modification of the fastening device for thesocket; and Fig. VI is a bottom view of the modification shown in Fig.V.

Referring to the drawingsz-l is the gunwale of the boat, on top of whichis secured the gunwale plate 2, which forms the socket for .the forkedrow look. This plate has a semi-circular rim 3, which extends from oneside to the other, and is reamed out on a level with the surface of theplate, to allow for the circular flange tformed on the base of the fork5 of the lock.

6 and 7 are clasping arms pivoted to the gunwale plate 2, by a rivet 8.These clasping arms 5 and 6, when closed into the position shown in Fig.II, complete a circle formed by the rim 3 cast on the plate 2, the arms6 and 7 being provided with small extensions 6 and 7 which engage inrecesses inthe ends of the semi-circular rim 3. These arms are reamedout the same as the. rim 3, to surround the flange on the base of thefork or look 5. When the two arms are closed, as shown in Fig. II, thebase of the 1ock 5 is entirely surrounded, and the lock 5 may berevolved in this bearing without any possibility of' being 'in the plate2.

Serial No. 511,110. (No model.)

removed unless the two arms are opened, as is shown in Fig. III. Thereis no projection from the plate 2 into the base of the lock 5, nor isthere any projection from the base of the lock 5 into any recess belowthe upper surface of the plate 2. I

The two arms 6 and 7 are secured in their closed position by a small pin9, which passes through a hole 11 in each of the armsand also This pin 9may be secured by a chain 10 to one side of the forked lock, as is shownin Fig. I, or there may be provided a smallcrank'12 made of wire orother suitable material, hinged to the bottom of the plate 2 by suitablelugs 13, and provided with a handle 14 extending on the inside of thegunwale. From the center of the crank a small pin 15 is mounted, and thetop of the gunwale is recessed out a short distance to allow thenecessary vertical play for this pin 15, which in its activepositionwould be as shown in Fig. V, the handle 14-. being in a verticalposition, the pin 15 extending through the plate 2 and up through botharms 6 and 7.

To open the socket and remove the row lock, it would only be necessaryto move the han dle 14. into the position indicated in the dotted linesof Fig. V, when the pin 15 would be lowered to such an extent that thearms 6 and 7 might be opened.

I claim as my invention- 1. The combination in a row lock, of the lock 5having the circular flanged base 4., and the gunwale plate 2 providedwith the semicircular rim 3 and the arms 6 and 7 pivoted to the gunwaleplate 2 and adapted to complete the rim partially formed by saidsemi-circular rim 3, said completed rim being adapted to receive andhold the circular flanged base of the row-lock; substantially asdescribed.

2. The combination in arow lock, of the lock 5 having the circularflanged base 4, the gunwale plate 2 provided with the semi-cin *cularrim 3 and the arms 6 and 7 pivoted to the gunwale plate 2, and adaptedto complete the rim partially formed by said semi-circular rim 3, saidcompleted rim being adapted to receive and hold the circular base of therow lock, and means for securing the arms 6 and 7 in their closedposition; substantially as described.

3. The combination in a row lock, of the lock 5 having the circularflanged base 4, the gunwale plate 2 provided with the semi-circular rim3 and the arms 6 and 7 pivoted to the gnnwale plate 2, and adapted tocomplete the rim partially formed by said semi-circular rim 3, saidcompleted rim being adapted to receive and hold the circular flangedbase of the row lock, the pin 15 and the small crank 12 mounted on thebottom of the plate 2 m for operating the pin 15; substantially asdescribed.
